MAHLSTICK.

Application filed October 10, 1924. Serial No. 742,897.

,To all whom it may concern:

Be it known that I, LOUIS GOOTI-IERTS, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented new and useful. Improvements in Mahlsticks, ofwhich the following is a specification.

This invention relates to improvements in mahlsticks.

The principal object of this invention is to provide a mahlstick havinga level in (:orporated in its structure, so that the stick may beemployed for lining letters, without the necessity of first employing alevel and a line and making a mark upon the object to be lettered.

Another object is to construct a mahlstick which may be employed with ahinged member for use in drawing circles.

A still further object is to produce a mahlstick which may be extendedor contracted in accordance with the desires of the user.

An additional object is to produce a mahlstick which is light, yetstrong and rigid.

Other objects and advantages will be apparent during the course of thefollowing description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a side elevation of my mahlstick,

Fig. 2 is an enlarged detail view of one of the joints of my stick.

Fig. 3 is an enlarged detail view in crosssection showing the head of mystick,

Fig. 4 is a side elevation of my mahlstick employed with a hinged jointand compass ends, and

Fig. 5 discloses compass ends as they appear removed from the mahlsticksections.

At the present time it is customary to employ a mahlstick having a head,which stick is of considerable length, the mahlstick being employed forlettering and is used to rest the hand upon while performing thelettering operation. \Vith this type of mahlstick, it is necessary thatthe artist carry in his kit a level, a yardstick, and a large compass.These additional tools being of considerable length cannot be placed inthe kit box, which is usually small. I have therefore devised amahlstick wherein I have combined a level a graduated yardstick,

and so designed my stick that I may employ the same as a. compass.

In the accompanying drawings, wherein for the purpose of illustration isshown a preferred embodiment of my invention, it will be noted that mystick is composed of three sections 5, 6 and 7, which sections arepreferably made of square tubular, metal which is of light-weight.

In order to reenforce the sections thus constructed and to provide meansfor joining these sections, I place in each section a liner 8, which hasa tapered end 9, split as at 11. This liner is constructed of springmetal so that the end 9 will maintain a tight sliding fit with the nextsection.

At 12 I have shown a head having an opening 13 therethrough. A similaropening 14 is provided in the head sothat the user may look down upon aspirit level 16 mounted. within the head. The opening 13 permits thelevel 16 to be viewed when the stick is held in a vertical position andat a point substantially even with the eyes. This head is covered with asuitable pad 17 to prevent the slippage of the head while in contactwith the object being worked upon.

This head is provided with a tapered end 18, similar to the tapered end9, above described. At 19 I have shown a hinged joint to which thesections 5 and 7 of the mahlstick may be attached and at 21 and 22 Ihave shown compass ends which are inserted in the mahlstick sections 5and 7. If it is desired to make a larger compass, four sec tions of amahlstick may be employed instead of two, as now shown.

At 23, I have shown ,la level inserted in the section 6 of'themahlstick, which level is at right angles to the level 16 carried in thehead. This level permits the mahlstick to be employed in drawinghorizontal lines.

It will thus be seen that I have provided a mahlstick which may beemployed as is now customary and one which will further permit the userto draw horizontal or vertical lines by employing either the levels 23or 16. I have further provided a mahlstick which may be disassembled andemployed with a hinged joint and compass points for the purpose ofconstructing a compass. Longitudinal markings are formed upon the sticksections which will assist the user in laying olf any design or work.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same; and thatvarious changes in the shape, size, and arrangement of parts may beresorted to Without departing from the spirit of the invention or thescope of the subjoined claims.

Having thus described my invention, I claim 1. In a niahlstick, aplurality of sections removably secured one to the other, a levelpositioned in one of said sections, a head secured to another of saidsections, said head having a level secured therein, the

level in said head and the level in said first section being at rightangles to each other.

2. In a mahlstick, a plurality of sections having lineal markingsthereon, a level formed in one of the sections of said stick, a headformed on another of said sections, a level mounted in said head, meansfor viewing said level in said head, said level in said head and saidlevel in said section being at right angles to each other.

In testimony whereof I aflix my signature.

LOUIS GOOTHERTS.
